Improvement in spindles for spinning-frames



JOHN E. ATWOOD, OF MANSFIELD, CONNECTICUT.

IMPROVEMENT IN SPlNDLES FOR SPINNING-FRAMES.

Specification forming part of Letters Patent No. 58,046, dated September18, 1866.

the accompanying drawings, making a part of this specification, inwhich- Figure l is a longitudinal transverse section. Fig. 2 is a planor top view.

Similar letters ot' reference indicate corresponding parts in bothiigures.

`This invention consists in an improvement in self-oiling spindles forspinning-frames, whereby they are prevented from being drawn aside orout of line by the tension otl the hands upon the whirr, and wherebythey are retained in proper position in their journal boxes or bearingswithout being subjected' to undue wear or friction.

To enable others to understand the construction and operation ofmyinvention, l will proceed to describe it with reference to thedrawings.

a brepresent the spindle itself, of which a is the tapering upperportion, and b the cylindrical lower part or journal. B is the nprighttubular journal box or socket, in which thejournal b of the spindle a bis placed, as shown more clearly in Fig. l.

rlhe lower end of the journal b is made ot' conical form, and iittedinto a step of corresponding shape in the bottom ot' thc bearing B, asshown at c.

Formed around the lower end of the journal b,just above its conicalextremity, is an annular groove, n, which is so shaped that an annularshoulder, r, is formed at the lower end ot' the said groove, asrepresented in the said Fig. 7

The exterior of the upper end of the bearing B is made cylindrical, asshown at d, and iixed upon the lower end of the tapering upper portion,a, of the spindle a b is a downwardly-projecting cylindrical sleeve, C,which is of such size as to tit snugly upon the cylindrical part d ofthe bearing, and-which has the whirr c formedupou its lower extremity.The said whirr being thus situated considerably below the top of thebearing B any lateral strain upon the spindle a b from the tension ofthe band upon the wlliirr is prevented.

D represents a tube, which may be formed in one piece with the socket orjournal-box B,

and which communicates with the interior of the said socket, as shown atj'. The upper end of this tube D is expanded to constitute anoil-reservoir, g, which is covered by a screwcap, It.

E is a bar or rod, which is placed in the tube D, and which is ofsomewhat less dialneter than t-he interior of the said tube. The upperend of this rod E is furnished with two laterally-projecting lugs orears, i, which rest upon the bottom of the oil-reservoir g, and serve tokeep the bar E from descending too far, while it is prevented fromrising up therefrom by the screw-cap h, secured upon the top of the saidreservoir.

The lower portion of the bar E is made tapering, and has formed upon itslower end a spur or stud, s, which is bent inward, so that its extremityenters the groove u in the jour nal b ofthe spindlejust above theshoulder r, so that when the spindle is forced upward the said shoulderr will strike the stud s and prevent the withdrawal of thejournal b fromthejournal box or socket B. At the same time, by tirst removing thescrew-cap 1L and taking out the rod E, the spindle may be easilywithdrawn.

The oil or` other lubricating` material isplaced in the reservoir g,and, flowing down through the space between the rod or bar E andthesides of the tube D, passes into the socket B, being forced upwardtherein between the journal b and the sides of the said socket to aheight corresponding to that ot" the oil in the reservoir, and by thuskeeping the said journal b ot' the spindle a b surrounded with oil,eftectually and continuously lubricates the same.

What I claiin as new, and desire to secure by Letters Patent, is-

l. The inclined tube D, provided at its upper end with a reservoir, g,in combination with the socket B and spindle a b, when said socket issurrounded by a sleeve carrying the whirr, substantially as herein setforth, for the purpose specified.

2. The bar or rod E, suspended within the tube D, and in relation withthe annular shoulder fr, formed around the lower end of the spindle a b,substantially as herein set forth, for the purpose specified.
